Re: [Pharo-users] Pharo 2.0 debugger strange behavior

by stephane ducasse

there is also haltIf: which lets you halt only when the method is executed from the message passed as argument.

[ANN] ConfigurationOfOpenDBXDriver in MetaRepoForPharo20

by Guillermo Polito

Hi! I just took some time to load and test opendbx in 2.0, with the latest fixes to be able to load ffi. The configuration stable version loads cleanly in Pharo 2.0 and the configuration is available in the configuration browser. I'll continue with Glorp & friends following :) Guille

Re: [Pharo-users] Pharo 2.0 debugger strange behavior

by Xavier MESSNER

Hi, Thanks for the information. I just discovered that i can use #haltOnce and #halt to stop execution and view step by step what happening. Highlighting is working fine this way. Thanks to smalltalk community a video exist here <http://www.jarober.com/blog/blogView?showComments=true&printTitle=ST_4U_270…> . I can migrate my code and use it daily now. I think i will have a lot of fun :) Regards.

Re: [Pharo-users] Spec One-to-many

I also notice you can use arrowDown and arrowUp, but not really helping if the list is long :) I propose a fix here: https://pharo.fogbugz.com/default.asp?10531 Ben On May 5, 2013, at 4:50 AM, DeNigris Sean <sean(a)clipperadams.com> wrote: > I'm having difficulty expressing a one-to-many relationship in a Spec UI (in Pharo 2.0). > I want to have a dialog where the user can enter a business expense, which will be assigned to a particular account (see screenshot). > > I tried: > - using a DropListModel.

Re: [Pharo-users] Spec One-to-many

by Benjamin

After a bit of experimentation :) As an example here, I take DropListExample On the DropList when you type something like 'Gr', nothing is shown but the list actually highlight it (in green -> second selection). So if then you press enter, it selects it. That's quite weird :) I will have a look of how to have the same behaviour without having to press enter and without having to duplicate the list code Ben On May 5, 2013, at 4:50 AM, DeNigris Sean <sean(a)clipperadams.com> wrote: > I'm having difficulty expressing a one-to-many relationship in a Spec UI (in Pharo 2.0). > I want to have a dialog where the user can enter a business expense, which will be assigned to a particular account (see screenshot). > > I tried: > - using a DropListModel.

Spec One-to-many

by DeNigris Sean

I'm having difficulty expressing a one-to-many relationship in a Spec UI (in Pharo 2.0). I want to have a dialog where the user can enter a business expense, which will be assigned to a particular account (see screenshot). I tried: - using a DropListModel. This disrupted the flow because it seems it can't be typed into, so the user has to mouse through to find the correct account - using a TextInputFieldModel with entry completion. It seems that this suffers the same fate as above. In its current form, it's almost unusable. Pressing the down arrow to select an item from the completion menu makes the menu disappear, tab makes the widget lose focus, and I have complete on enter disabled, so again one must mouse click on the menu What would be the best way to express this without forcing the user to take their hands off the keyboard? Thanks! Sean

Hello, You can also find an short example of back propagation algorithm implemented in Smalltalk in chapter 21 of "Advanced Smalltalk" written by J. Pletzke.
